It took the Nitty Gritty Dirt Band until this album to come up with a merger of rock and country music that worked for both sides and everyone involved. Not only did this album result in exposure to a new and wider audience for the likes of Mother Maybelle Carter, Roy Acuff, Earl Scruggs, Merle Travis, and others, but this was the first real country album that a lot of rock listeners under the age of 30 ever heard.
